Implementation of the ambitious program named "Manhattan Project" in 1942, has overall responsibility for the development of the atomic bomb by the U.S. Army Corps of Engineers. The plans to invest $ 2.5 billion to spend over 10 million scientific and technical personnel and workers, stepping up development in the case of absolute confidentiality. In the early morning of July 16, 1945, the first atomic bomb exploded in the desert regions of the United States the New Mexico ����Ĭ��� Air Force Base is successful, its power of 1500-2000 tons of TNT equivalent. Atomic bomb the advent of a major scientific and technological achievements of this century to affect the course of human history, thus, mankind has entered the nuclear age.
